Ophthalmic photographic apparatus
First Claim
1. An ophthalmic photographic apparatus for capturing dynamic and still eye fundus images by infrared light-excited fluorescence, comprising:
- a photographic means sensitive to infrared light used for photographing dynamic and still eye fundus images by infrared light-excited fluorescence;
a strobe light source; and
means for switching an image capture to first and second modes;
wherein the strobe light source is activated in the first mode to emit a flash to capture the infrared light-excited fluorescence image of the eye fundus as a still image and deactivated in the second mode to capture it as dynamic and still images.

Abstract
An ophthalmic photographic apparatus is provided that is readily able to capture dynamic and still eye fundus images by infrared light-excited fluorescence. A CCD device that is sensitive to infrared light is used to capture images of the eye fundus as dynamic and still images. When the shutter button is pressed, infrared light-excited fluorescence images are obtained as still images and stored in a recording unit. The infrared light-excited fluorescence image of the eye fundus is captured as a still image with or without a flash from a strobe light source. Such an arrangement makes it possible to capture still images even when dynamic images are being recorded.

4. An ophthalmic photographic apparatus for capturing dynamic and still eye fundus images by infrared light-excited fluorescence, comprising:
-
a first photographic means sensitive to infrared light used for photographing dynamic and still eye fundus images by infrared light-excited fluorescence;
a second photographic means sensitive to infrared light used for photographing a still eye fundus image by infrared light-excited fluorescence;
a strobe light source;
means for selecting the first and second photographic means; and
means for switching an image capture to first and second modes;
wherein, when the first photographic means is selected, the strobe light source is activated in the first mode to emit a flash to capture the infrared light-excited fluorescence image of the eye fundus as a still image and deactivated in the second mode to capture it as dynamic and still images, and, when the second photographic means is selected, the strobe light source is activated to capture the infrared light-excited fluorescence image of the eye fundus as a still image. - View Dependent Claims (5, 6, 7, 8, 9)
